Gopperton, Dayton, Ohio, assignors to The Standard Regis-Dayton, Ohio, a corporation of Application July 15, 1942, Serial No.451,030 17 Claims. (Cl. 101-373) This invention pertains to printingapparatus, and more particularly to a changeable roll for imprintingheadings and optionally spaced down rules at successive spaced intervalsupon strips of continuous series connected detachable form stationery.

It is customary commercial practice to employ preprinted record formsfor bills, statements, invoices, stock sheets, and other records whichinvolve tabulation of amounts or arrangement of indicia in columns.Ordinarily continuous form stationery is printed and folded uponcylinder presses which require considerable time for composition orstting" of the forms and for make ready," and hence such printingmethods are not economical for small quantities of stationery supplies.v

The spacing of transverse line ruling as employed upon such stationeryis arbitrarily determined by the line spacing operations of the writingmachine in which the stationery is to be inscribed .and with which thehorizontal line rulings must agree. The vertical rulings definingcolumnar spaces are optionally disposed, and differ in location andspaced relation for different purposes. Likewise, printed headings forthe defined columns may vary widely, as do also identification headingsof the record sheets.

In the present invention it is contemplated that stock stationery inlarge quantities may be preprinted with horizontal line rulings'andsimul-.

taneously marginally punched, if to be used with pin type feedingdevices, or provided with punched file holes, and may be zigzag foldedall in continuous operation. Subsequently, smaller quantities of suchpreprinted stock material may be reprinted by the hereindescribedprinting roll to. individualize the stationery by imprinting relativelyspaced down rules at predetermined intervals to define columns-forspecific purposes which may be optionally positioned and may varygreatly on different lots of reprinted stationery, and by insertingheadings intermediate succeeding preprinted areas and also columnheadings in agreement with the optionally positioned vertical linerulings. It is, however, unnecessary that the stock material bepreprinted. Plain, blank strip material, either punched or unpunched,may receive the imprinted headings and vertical line rules from thepresent printing roll.

In the present instance there are employed a series of segmental linerule members which are interchangeably positioned in relatively spacedrelation upon a supporting arbor with intermediate spacing discstherebetween. The spacer discs are adapted to interchangeably receiveprinting type for imprinting headings. The column rule segments arerotatively adjustable relative to the spacer discs and other segmentsinto alternate positions to longitudinally oifset the ends of differentruled lines. The object of the invention is to improve the construction,as well as the means and mode of assembly of printing rolls, wherebythey may not only be economically manufactured, but will enable readyand quick reassembly into various combinations and spacings of linerules and headings.

A further and important object of the inven-' tion is to provide amethod and device for imprinting line rule columns upon record materialat optionally selective positions.-

.A further object of the invention is to provide improved locking meansfor securing the interchangeable elements of the present printing rollin their assembled relation.

A further object of the invention is to provide an improved method ofproducing a wide variety of printed forms of different design at minimumcost.

.A further object of the invention is to enable the economicalproduction of relatively small quantities of printed forms.

A further object of the invention is to provide a printing roll havingthe advantageous structural features and inherent meritoriouscharacteristics, the method of assembly of such roll, and the mode ofsimplifying the production of printed forms herein set forth,

With the above primary and other incidental objects in view as will morefully appear in the specification, the invention intended to beprotected by Letters Patent consists of the features of construction,the parts and combinations thereof, and the mode of operation, or theirequivalents, as hereinafter described or illustrated inthe accompanyingdrawings.

The printing roll assembly forming the sub-- ject matter hereof isprimarily intended for production of continuous form stationery for usein International Business Machines tabulators or Powers tabulators, butmay be used in production of printed forms for other uses, as intypewriters, billing and addressing machines, and even for hand writtenrecords. 7

The stock material for printed form stationery comprises continuousstrips of material transversely scored at longitudinally spacedintervals to afford weakened division lines upon which the strip isdivisible after inscription into individual sheets a, Fig. 24. Thestrips may be punched at prescribed intervals as at b-b, Fig. 24, forengagement of pin type feeding devices, or at 0-0, Fig. 24, .to providefile holes in successive separable sheets a. The stock strip may beentirely blank or may have'thereon preprinted horizontal spaced lines d.The present printing roll is adapted to imprint upon each sheet sectionof the continuous stock strips relatively spaced vertical line rulese--e at optionally selected spaced positions, to define columns and toconcurrently imprint column headings J--f and sheet identificationheadings g. By relative rotative adjustment of the rule segments,certain of the vertical rule lines e--e may be longitudinally offset alimited -distance in relation to other vertical line rules, as indicatedat h and h, Fig. 24.

Referring to the drawings, l-l indicates portions of the printing pressframe in which is journaledthe printing roll haft or arbor 2, upon whichare aranged side by side a succession of spacer discs 3-3 and interposedline rule segments 4-4. Such assembly is well illustrated in Figs. 1 and10. The spacer discs 3 are keyed upon the shaft or arbor 2 for unisonrotation, but are free for limited axial shifting movement thereon, onerelative to the other. A relative short segment of the periphery of eachspacer disc 3 contains a plurality of undercut notches 5-5 to receiveinterchangeable type members 5. The type members are laterally notched,as shown in Figs. 2, 3, 4, 19 and 20, to slldingly engage in thelaterally recessed notches 5. The notches 5 of each disc 3 register withthose of the adjacent assembled discs to thereby form continuousundercut type channels or slots disposed longitudinally throughout theassembly. There may be as many peripherally spaced type channels asfound necessary.

Each spacer and type disc 3 has on one'side a raised, or relief, panelI, which surrounds the concentric shaft opening and extends thenceradially to the periphery of the disc. The projection of such reliefpanel I beyond the lateral face of the disc 3 is quite shallow, asindicated in Fig. 7, and is not greater than the thickness of the rulesegments 4, but preferably slightly less than such dimension. Eachspacer and type disc3 has therein a concentric arcuate slot 8, the endof which intersects the relief panel I, which receives a. locking rod 9.

The line rule segments 4 are of somewhat greater diameter than the discs3, beyond which their margins extend into peripheral agreement with thefaces of the printing type 6 carried by the spacer discs 3. Each rulesegment lhas therein a substantially sector shaped slot or recess I0,the inner extremity of which is concentric with and proportioned to fitabout the concentric inner end of the projecting relief panel I of anassociated disc. The recess or slot 10 of the rule segments is somewhatwider than the panel 1 against the lateral shoulders of which the innermargins ll] of the segment slot alternately engage to limit relativerotative adjustment of the segment and disc. It is by such adjustmentthat certain vertical rules e of the printed form a are longitudinallyoffset at h and h.

One side of the recess or slot I0 is provided with an arcuateindentation II which overlies the arcuate slot 8 of the associated disc3. The discs 3 being loose on the shaft or arbor 2 for limited lateraladjustment. the laterally open recesses 10 in the line rule sectors 4enable such sectors to be slidingly inserted in selected positionsbetween any two'adjacent spacer discs 3 into straddle relation with theraised panel 1.

. In final adjusted relation the line rule segments the standard linealspacing of charactersand figures inscribed by conventional writing orim- :printing machines. The customary lineal character spacing is fivethirty-seconds of an inch. Thus, the width of columns defined by spaced.down rules e--e printed by the segments 4 on the record material are ineach instance a multiple of the conventional writing machine characterspace. By inserting the line rule segments.

between selected spacer discs, the widths of the imprinted column linesmay be varied to accommodate many or only a few indicia or characters insucceeding lines, and the spacing between columns may be likewisevaried, also in multiples of indicia character spaces.

After being inserted between adjacent discs the rule segments may beindividually rotatively adjusted, as shown in Figs. 2 and 3; to causethe imprinted down rules to start higher or lower on the printed formsin relation to the. imprinted heading. The offset or line terminalvariation is limited by the engagement of one side or the other of thesegment apertures ill with the marginal shoulder of the raised panel 1of the adjacent spacer disc.

One margin of the indentation II in the line rule segment recess I isformed with adjacent arcuate configurations II which slightly overlapthe slot 8 of the spacer disc. The locking rod 3 which extends throughthe registerin arcuate slots 8 of the disc 3 also extends through thelateral indentations II of the interposed line rule segments." Thelocking rod 9 is flattened on one side, and is engageable in one or theother of the arcuate configurations ll of the line rule segments 4 byinitial rotative adjustment of the segments followed by partial rotationof the rod, to lock the segments against rotation from theiradjusted'position. The rule segments and the rod 9 are relativelyadjustable only when the rodis partially rotated to present its flatside toward the-arcuate configurations l I of the segment. Afteroscillatory adjustment of selected segments 4 from the position shown inFig. 2 to that of Fig. 3 or vice versa, the locking rod is partiallyrotated to turn the convex face of the rod into ,the correspondingindentations II. The spacer discs 3 and interposed line rule segments 4are clamped in adjusted relation under axial compression betweenterminal thrust heads l2. One of the heads 12 is secured to the shaft 2by a set screw l3. The other head [2 is axially adjustable underinfluence of a jamb nut l4 threaded on the shaft 2. The ends of thelooking rods 9 project through slots 8' in the compression heads whichcorrespond to the disc slots or out of locking engagement with the rod9, as shown by solid and dotted lines in Fig. 4.

When it is desired to' disengage the segments entirely from theassembly, the lock rod 9 is first rotated and then shifted to the end ofthe slot 8.which intersects the panel I by oscillation of the arms IS.The line rule segments 4 may, at will, be transposed from one positionto another and other segments may be inserted between adjacent discs orremoved therefrom, and the assembled segments may be partially rotatedfrom one position to another to vary the lateral and longitudnialrelations of different downrule lines ee.

In Figs, 13 to 18 there is illustrated a different mode of locking theline rule segments 4 in their rotative ,positions of adjustment. spacerdiscs 3 are provided with key hole slots 23 which register with those ofother discs. The line rule segments are of the same'general shape withthe same recess or cutout H] as before. Instead of the indentation l I,each segment is provided with an opening 24 in .position to overlie thekey hole slot 23 of the discs. The upper margin of the opening 24 isformed with two inverted V-shaped notches 25 side by side. Ex-

tending through the key hole slots 23 of the discs and the overlyingopenings 24 of the segments is a rock shaft 26 flattened on one side.Also disposed in parallel contactin relation with' the rock shaft 26through the key hole slots 23' and openings 24 of the discs and segmentsrespectively is a polygonal wedge bar 21, the upper side 21' of which isbeveled to form an angular edge engageable alternately in one or theother of the'inverted V-shaped notches 25 according to the rotativeposition of the segment 4 relative to the discs 3.

B, and are engaged in oscillatory arms l6 j ournaled upon the shaft 2beyond the terminal clamp heads [2. The swinging arms l6 carry helicalsprings [1 by which the rod 9 is held within the engaged indentations ofthe segments and chatter prevented. One extremity of the locking rod 9is (provided with a knob. lit, by which the rod may be rotated into andout of its segment locking position. To maintain locking position of therock rod 3 a collar [9 rotative on the shaft 2 carries a polygonalflange 20, one end 20' of which is'movable into and out of abutting Yrelation with the fiat side of the rock' rod 9,

as shown by solid lines in Fig. 4 to temporarily prevent partialrotation thereof. v

The opposite side of the flange 20 carries a detent plunger 2|engageable alternately in spaced holes 22 in the corresponding clamphead l2 to secure the flange extremity 20 either in Thewedge bar 21 isbodily movable radially of the discs and segments within the narrowportion of the key hole slots 23 by the camming action of the flattenedshaft 26 upon partial rotation thereof. The rock shaft is provided witha crank arm 28 at one end for manual adjustment. When the rock shaft isturned with its flat side contiguous to the V-shaped bar 21, as in Fig.16, the latter is retractable out of engagement with either V notch 25and the line rule segment is free for rotative adjustment from therelative position shown in Fig. 2 to that illustrated in Fig. 3, or viceversa. This adjustment, as before described,

enables corresponding down rules e--e of the mgly positioned V notch 25,as is shown in Fig. 15.

' To look the rock shaft in adjusted positioman oscillatory segment 29on the shaft 2 may be turned into the path of the crank arm 28 toprevent return oscillation of the crank and shaft. The locking segmentmay be clamped in adjusted position by a set screw 30 positioned withina slot 3| in the locking segment and engaging in a boss on one of theterminal clamp heads l2 of the roll assembly, as shown in Fig. 1'7. Aradial finger 32 affords convenient means for adjusting the lockingsegment into and'out of engagement with the crank arm 28.

In Figs. 19 to 23 there is shown a further means for locking theinterposed line rule segments 4 in either of alternative rotativepositions of adjustmentto effect longitudinally offset relation ofdifferent down rules e-e on the printed forms. Inthis embodiment theaperture [0 of the line The diate the pivoted arms 35 is a cam slide 31,the

tapered head of which is engageable between bearing lugs 38 of the armsto thereby spread the pivoted arms 35 upon depression of the slide. Thecam slide 38 is longitudinally slotted and is guided by a pair of studs39 carried by the spacer disc and projecting through the cam slide slot.

The line rule segments, as before described, are rotatively adjustablefrom the position shown in Fig. 19 to that shown in Fig. 20, and viceversa. To rotate the segments, the cam slide is withdrawn, as in Fig.22, which permits the heads 35 of the arms 34 to swing inwardly out ofengagement in the V-shaped indentations 33 and 33'. Upon adjustment ofthe line rule segments, the cam slide is thrust inwardly, therebyforcing the heads 35 of the swinging arms into locking engagement in theindentations 33-33. In one position of adjustment of the line rulesegments, the locking arms 34 engage the outermost indentation 33 andinnermost indentation 33, as in Fig. 19. In the alternative position ofadjustment of the imprinting segments 4, the locking arms engage theinnermost indentation 33 and outermost indentation 33', as shown in Fig.20. When the cam slide 31 is thrust-inwardly to lock the arms 34 in theindentations 33-33' is 50 held by positioning a type member 6 in theperipheral notch of the spacer disc in overlying relation with the endof the cam slide, as shown in Figs. 19

and 20. The head of the cam slide 3? is marginally notched forengagement of a lifting tool which may be inserted within the restrictedspace for pulling the cam slide to release the locking arms.

The diameter and peripheral extent of the printing roll assembly areproportionate to the length of the forms to be imprinted thereby, sothat ordinarily one form is imprinted at each complete rotation of theroller. However, for very short forms an additional group of typegrooves or slots may be provided in the spacer discs as at 40 in Fig.12, to receive a group of type for imprinting a second heading at eachrotation of the printing roll. In such event, the line rule segment '4is peripherally indented at 4| to interrupt the down rule linescoincident with such second heading. By this arrangement two completeform imprints are effected during each complete rotation of the rollassembly.

From the above description it will be apparent that there is thusprovided a device of the character described possessing the particularfeatures of advantagebefore enumerated as desirable, but

which obviously is susceptible of modification in .its form,proportions, detail construction and arrangement of parts withoutdeparting from the principle involved or sacrificing any of itsadvantages.
